The present invention relates to an epoxy coating agent, a method for producing the epoxy coating agent, and a waterproofing method using the same, and more particularly, to an epoxy coating agent which is finally completed by introducing methyl acrylate, methyl methacrylate, dimethylaniline and dimethyl para- And a waterproofing method using the same. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an epoxy coating agent having improved abrasion resistance, which can improve water resistance,

콘크리트 구조물의 수분에 의한 부식이나 파손 등을 방지하기 위해서는 콘크리트 구조물 표면에 방수 또는 방식 처리를 하는 것이 요구된다. 이러한 방수 처리는 일반적으로 방수용 수지를 콘크리트 구조물의 표면에 도포함으로서 이루어진다.In order to prevent corrosion or damage caused by moisture of concrete structure, it is required to waterproof or treat the surface of concrete structure. Such waterproofing treatment is generally performed by applying a waterproof resin to the surface of a concrete structure.

종래 일반적인 콘크리트 구조물 표면의 방수 공법은, 등록특허 10-1215403호 등에 개시된 바와 같이, 방수하고자 하는 구조물의 표면에 묻은 오염물을 제거하고 평탄화하는 전처리 단계와, 상기 전처리된 표면에 프라이머를 코팅하여 프라이머층을 형성하는 단계 및 상기 프라이머층 상에 에폭시 코팅제를 도포하는 단계를 포함하여 이루어진다.A conventional waterproofing method for a concrete structure surface includes a pretreatment step of removing contaminants on the surface of a waterproofing structure and planarizing the surface of the waterproofing structure as disclosed in Japanese Patent Application No. 10-1215403 and the like, And applying an epoxy coating agent on the primer layer.

이러한 에폭시 수지 조성물은, 얻어지는 경화물의 기계적 성질, 내식성, 밀착성 등이 뛰어나기 때문에 도료, 접착제, 적층판, 전자 부품 용도 등의 각 분야에서 널리 사용되고 있으나, 대부분 유기 용제에 희석한 조성물로 사용되는 실정이므로, 최근 환경 문제가 부각됨에 따라 수성화가 기대되고 있다. Such epoxy resin compositions are widely used in various fields such as paints, adhesives, laminated plates, and electronic parts because they have excellent mechanical properties, corrosion resistance and adhesiveness, but they are mostly used as compositions diluted with organic solvents Recently, as the environmental problems become more prominent, water-based improvement is expected.

여기서, 에폭시 수지는, 예를 들면, 계면활성제를 사용하여 호모 믹서로 고속 교반하여 제조되는 에폭시 수지 에멀젼이 널리 알려져 있는 상태이지만, 계면활성제의 영향으로 내수성과 접착성 등의 물성이 저하되는 등의 문제점이 있다. Here, the epoxy resin is an epoxy resin emulsion prepared by, for example, using a surfactant and stirring at a high speed with a homomixer, but the surfactant has the effect of deteriorating the physical properties such as water resistance and adhesiveness There is a problem.

반면, 계면활성제를 함유하지 않는 에폭시 수지는, 비스디페놀의 디글리시딜에테르, 비스디페놀 및 폴리옥시알킬렌글리콜의 디글리시딜에테르를 반응시킨 것과 비스디페놀의 디글리시딜에테르, 비시드페놀, 폴리옥시알킬렌글리콜의 디글리시딜에테르 및 디이소시아네이트를 반응시킨 것 등이 있다. 또한, 2관능 이상의 에폭시 수지, 다가 페놀 및 지방족 폴리올로 이루어지는 축합 생성물과 2관능 이상의 에폭시 주지, 모노 및 폴리이소시아네이트로 이루어지는 축합 생성물 등이 있다.On the other hand, the epoxy resin containing no surfactant is obtained by reacting diglycidyl ether of bisdiphenol, diglycidyl ether of bisdiphenol and polyoxyalkylene glycol, diglycidyl ether of bisdiphenol , Uncycled phenol, diglycidyl ether of polyoxyalkylene glycol, and diisocyanate. Further, condensation products of bifunctional or higher-functional epoxy resins, polyhydric phenols and aliphatic polyols, and condensation products of bifunctional or higher epoxy resins, mono- and polyisocyanates, and the like are available.

그러나 상기와 같은 계면활성제를 함유하지 않는 에폭시 수지는, 모두 폴리에틸렌글리콜의 1급 수산기가 일부 조성물 중에 남아서 가교 밀도가 오르지 않는 등의 원인으로 내마모성, 내수성, 방식성, 내알칼리성, 수분산성 및 에멀젼 안정성이 저하되는 문제점이 있다.However, the above epoxy resin not containing a surfactant as described above has a problem that abrasion resistance, water resistance, anticorrosion, alkali resistance, water dispersibility, and emulsion stability due to the fact that primary hydroxyl groups of polyethylene glycol remain in some compositions, Is lowered.

따라서 본 발명의 목적은 메틸아크릴레이트, 메틸메타아크릴레이트, 디메틸아닐린, 디메틸파라톨루이딘을 에폭시 분자 내에 도입하여 최종적으로 완결되는 에폭시 코팅제의 내마모성을 향상시켜 내수성과 방식성 등을 개선시킬 수 있는 내마모성이 향상된 에폭시 코팅제, 그 제조방법 및 이를 이용한 방수공법을 제공하는 것이다. Accordingly, it is an object of the present invention to provide an epoxy coating composition which is capable of improving water resistance and anti-corrosive properties by improving the abrasion resistance of an epoxy coating agent finally introduced by introducing methyl acrylate, methyl methacrylate, dimethylaniline and dimethyl paratoluidine into epoxy molecules An improved epoxy coating agent, a process for producing the same, and a waterproofing method using the same.

한편, 본 발명의 효과는 이상에서 언급한 효과로 제한되지 않으며, 언급되지 않은 다른 효과들은 청구범위의 기재로부터 통상의 기술자에게 명확하게 이해될 수 있을 것이다.On the other hand, the effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.

이하, 본 발명의 바람직한 실시예에 대하여 상세히 설명하기로 한다. Hereinafter, preferred embodiments of the present invention will be described in detail.

본 발명의 바람직한 실시예에 따른 내마모성이 향상된 에폭시 코팅제는, 기본적으로, 메틸아크릴레이트, 메틸메타아크릴레이트, 디메틸아닐린 및 디메틸파라톨루이딘을 혼합 및 반응시킨 후 인산과 대두지방산이 첨가되어 생성된 A액과, 비스페놀 A 타입의 에폭시프리폴리머에 실리콘 오일, 폴리옥시에틸렌에테르 및 안료가 첨가되어 생성된 B액으로 이루어진 2액형의 에폭시 코팅제(또는 조성물)이다. The epoxy coating agent having improved abrasion resistance according to a preferred embodiment of the present invention basically comprises a mixture of methyl acrylate, methyl methacrylate, dimethylaniline, and dimethyl para-toluidine, followed by reaction with phosphoric acid and soybean fatty acid And a liquid B prepared by adding a silicone oil, a polyoxyethylene ether and a pigment to a bisphenol A type epoxy prepolymer, and a two-liquid epoxy coating agent (or composition).

보다 바람직하게는, 상기 A액은, 메틸아크릴레이트 100 중량부에 메틸메타아크릴레이트 70~80 중량부, 디메틸아닐린 60~70 중량부 및 디메틸파라톨루이딘 50~60 중량부가 혼합되어 80~100 ℃ 온도에서 5~7 시간 반응된 후 20~30 ℃ 온도로 냉각한 상태에서 인산 30~40 중량부와 대두지방산 20~30 중량부가 첨가되어 생성된다.More preferably, the liquid A is prepared by mixing 70 to 80 parts by weight of methyl methacrylate, 60 to 70 parts by weight of dimethylaniline and 50 to 60 parts by weight of dimethyl para-toluidine in 100 parts by weight of methyl acrylate, For 5 to 7 hours and then cooled to a temperature of 20 to 30 ° C, 30 to 40 parts by weight of phosphoric acid and 20 to 30 parts by weight of soybean fatty acid are added.

또한, 상기 B액은, 비스페놀 A 타입의 에폭시프리폴리머 수용액 100 중량부에 실리콘 오일 7~9 중량부, 폴리옥시에틸렌에테르 5~7 중량부 및 안료 3~5 중량부가 첨가되어 생성된다. The liquid B is produced by adding 7 to 9 parts by weight of a silicone oil, 5 to 7 parts by weight of a polyoxyethylene ether and 3 to 5 parts by weight of a pigment to 100 parts by weight of a bisphenol A type epoxy prepolymer aqueous solution.

상기 메틸아크릴레이트는, 에폭시 코팅제 시공시 방수성과 내마모성을 제공하여 투수비와 흡수비를 낮추기 위한 것으로, 아크릴산과 알콜로 이루어지는 에스터로서 과산화물, 빛, 열 등에 의해 쉽게 중합을 일으키고 중합사슬 사이의 다리 걸침을 일으켜 혼합물의 결합 및 반응이 이루어지도록 한다.The methyl acrylate is used for lowering the permeability and the absorption ratio by providing waterproof and abrasion resistance when the epoxy coating is applied. It is an ester composed of acrylic acid and alcohol, which easily polymerizes by peroxide, light, heat, etc., To cause the binding and reaction of the mixture.

상기 메틸메타아크릴레이트는, 아크릴산과 미타아크릴산 에스터의 중합 반응 공정을 거쳐 이중 탄소결합을 갖도록 만든 반응형 수지로서, 내구성, 내열성, 내화학성, 내마모성, 자외선안전성 등 물성이 뛰어나고, 햇빛 등의 날씨 및 기후에 견디는 성질인 내후성이 우수하며 외부 환경 변화에 의한 부식 등을 억제함과 동시에 구조물의 표면에 침투하여 일체화를 가능하게 하여 부착강도 및 인성을 개선하고 안료 등에 의한 착색성을 좋게 하는 기능을 제공한다.The methyl methacrylate is a reactive resin which has a double carbon bond through a polymerization reaction of acrylic acid and a methacrylic ester and has excellent properties such as durability, heat resistance, chemical resistance, abrasion resistance, ultraviolet safety, It is excellent in weather resistance which is endurance against climate and suppresses corrosion due to external environment change, and penetrates into the surface of the structure to enable integration, thereby improving the adhesion strength and toughness and providing a function of improving the coloring property by the pigment etc. .

여기서, 상기 메틸메타아크릴레이트는, 무색 투명한 액체로, C4 유분을 원료로 하여 제조된 터트-부틸 알콜을 기체 상태에서 산화시켜 메타아크릴산을 제조한 후, 메탈올로 에스테르화하여 제조할 수 있다.Here, the methyl methacrylate is a colorless transparent liquid, which can be prepared by oxidizing tert-butyl alcohol produced from C4 oil as a raw material in a gaseous state to produce methacrylic acid, followed by esterification with methanol.

한편, 상기 메틸메타아크릴레이트는, 메틸아크릴레이트 100 중량부에 대하여 70~80 중량부가 첨가되는데, 70 중량부 보다 적게 첨가되면 구조물의 표면과의 부착강도가 저하되어 내마모성 및 내후성 등이 크게 저하되고, 80 중량부 보다 많이 첨가되면 빠른 시간에 경화가 이루어져 구조물의 표면 깊숙이 침투하지 못하게 되어 오히려 부착강도가 저하되고 내마모성 및 내후성 등이 크게 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다. On the other hand, the methyl methacrylate is added in an amount of 70 to 80 parts by weight based on 100 parts by weight of methyl acrylate. If less than 70 parts by weight of the methyl methacrylate is added, the adhesion strength with the surface of the structure is lowered and abrasion resistance, If it is added in an amount of more than 80 parts by weight, curing takes place in a short time, so that it is impossible to penetrate deeply into the surface of the structure. In this case, the adhesion strength is lowered and abrasion resistance and weather resistance are greatly reduced. .

상기 디메틸아닐린은, 벤젠고리와 치환된 아미노기 한 개로 구성된 3차 방향족아민이며 아닐린의 유도체로 기름기를 통해 상기 조성물들의 혼합물인 에폭시 코팅층의 표면이 코팅되도록 하는 기능을 제공한다. The dimethylaniline is a tertiary aromatic amine composed of a benzene ring and a substituted amino group, and is a derivative of aniline, and provides a function of coating the surface of the epoxy coating layer, which is a mixture of the above compositions, through oil.

여기서, 상기 디메틸아닐린은 입자 크기가 50nm 이하인 것이 좋으며, 이 보다 큰 경우에는 조성물의 혼합에 따른 용액 내에서 분산 및 용해가 잘 이루어지지 않으며 에폭시 코팅층의 건조후 입자가 쉽게 분리되고 고르지 못하게 되는 문제점이 있으므로, 상기와 같은 한정된 입자 크기를 가지는 것이 바람직하다. The dimethylaniline preferably has a particle size of 50 nm or less. When the amount of the dimethylaniline is larger than the above range, the dispersion and dissolution of the dimethylaniline in the solution due to mixing of the composition is not performed well, Therefore, it is preferable to have the above limited particle size.

한편, 상기 디메틸아닐린은, 메틸아크릴레이트 100 중량부에 대하여 60~70 중량부가 첨가되는데, 60 중량부 보다 적게 첨가되면 에폭시 코팅층의 코팅에 따른 피복 효과가 저하되고, 70 중량부 보다 많이 첨가되면 에폭시 코팅층의 건조시 코팅 입자들이 커지거나 혹은 엉기는 현상이 발생되어 에폭시 코팅층의 표면이 고르지 못하게 되어 내구성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.On the other hand, the dimethylaniline is added in an amount of 60 to 70 parts by weight based on 100 parts by weight of methyl acrylate. When less than 60 parts by weight is added, the coating effect due to the coating of the epoxy coating layer is deteriorated. There is a problem that when the coating layer is dried, the coating particles become large or coarse to cause unevenness of the surface of the epoxy coating layer, thereby decreasing the durability of the coating layer.

상기 디메틸파라톨루이딘은, 상기 메틸아크릴레이트에 메틸메타아크릴레이트, 디메틸아닐린, 인산 및 대두지방산이 혼합되도록 하는 결합제이다.The dimethylparatoluidine is a binder which allows the methyl acrylate to be mixed with methyl methacrylate, dimethylaniline, phosphoric acid and soybean fatty acid.

여기서, 상기 디메틸파라톨루이딘은, 메틸아크릴레이트 100 중량부에 대하여 50~60 중량부가 첨가되는데, 50 중량부 보다 적게 첨가되면 결합력이 발휘되지 못하여 전반적인 방수성이 저하되고, 60 중량부 보다 많이 첨가되면 강한 결합력으로 인하여 점도가 증가되어 오히려 교반 혼합이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.If less than 50 parts by weight of dimethylparatoluidine is added, the overall water resistance is lowered. When the amount of dimethylparatoluidine is more than 60 parts by weight, There is a problem that the viscosity is increased due to the bonding force and the stirring mixing is lowered. Therefore, it is preferable to have the limited weight portion as described above.

상기 인산은, 상기 메틸아크릴레이트, 메틸메타아크릴레이트, 디메틸아닐린 및 디메틸파라톨루이딘 혼합액에 소정의 경도를 부여하여 내구성, 색상 보유성, 백아화저항성 등의 기능을 제공한다.The phosphoric acid is provided with a predetermined hardness to a mixture of methyl acrylate, methyl methacrylate, dimethylaniline and dimethyl para-toluidine to provide functions such as durability, color retention, whitening resistance and the like.

여기서, 인산은, 메틸아크릴레이트 100 중량부에 대하여 30~40 중량부가 첨가되는데, 30 중량부 보다 적게 첨가되면 에폭시 코팅층의 경도가 저하되어 내구성 등이 저하되고, 40 중량부 보다 많이 첨가되면 에폭시 코팅층의 경도가 너무 강하게 되어 구조물의 표면으로부터 들뜸 현상에 따른 부착 강도가 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.If less than 30 parts by weight of the phosphoric acid is added to 100 parts by weight of methyl acrylate, the hardness of the epoxy coating layer is lowered and durability is lowered. When the amount of phosphoric acid is more than 40 parts by weight, The hardness of the structure is too strong and the adhesion strength due to the lifting phenomenon is lowered from the surface of the structure. Therefore, it is preferable to have the limited weight portion as described above.
